Sphinx Documentation as PDF on Ubuntu 18.04/20.04

I've been using Sphinx for sometime to document the source code and I decided to generate a PDF this time rather the HTML and I faced a lot of missing dependencies, the article will show how to handle that on Ubuntu 16.04/20.04.

First, to generate a pdf in sphinx use

make latexpdf

The following steps for Ubuntu 18.04

1. Install latex
   sudo apt install latexmk

2. Adding some recommeded packages and fonts

sudo apt-get install texlive-latex-recommended texlive-fonts-recommended texlive texlive-science texlive-formats-extra
